I need to upgrade the video card in my Dell Dimension 8400. I have 4GB of memory.

I just use my machine for data crunching, making charts and movie editing. I don't do gaming.

Could someone suggest a 512MB GDDR3 video card for my machine?

I'd very much appreciate your help as I'm pretty ignorant of this issue. I've only just started learning about GDDR3.

I was thinking of the Visiontek Radeon HD 2600 XT 512 MB GDDR3 AGP Graphics Card, but I think this would be more than I need since I don't do gaming

Thanks for your help in advance.

I very much appreciate it.

Welcome to the forums!

You need a PCI-express card.
I would get one of these:

Please tell us how many amps you have on the 12v rails of your power supply.

As evengugg says, your machine uses a PCI-E not AGP expansion slot, which is a real bonus because AGP cards are both expensive and can have drive issues.
Look at the following: Nvidia: 9500 and 9400. ATI: HD4670, 4650 or 4550. None of them require an extra power lead connector and should be a simple job to install.
If you are not gaming look to price and warranty as most importaint rather than flashy coolers or overclocked units.
And check it will fit your case, some Dells use slim cases that require low profile cards.
